Reesa is having some problems with social anxiety so her mom invites a family friend, who is a shrink, over to help her with her problem. Part of Reesa's problem though has been her wetting accidents. A few months ago she had to undergo surgery but as a result, something with her bladder was damaged and now she can't control herself anymore.
The shrink has a therapy she recommends to personal friends, but can't otherwise because it's controversial, but it's worked. The therapy consists of wearing diapers again 24/7. More so, it requires the patient to let their biological parent baby them again, change their diaper, feed them etc. But in Reesa's state, she'd be in diapers anyway because of the bladder problem.
Reesa finally agrees to do it if it helps her get out of the house. The shrink grabs a diaper she brought along just in case and get's Reesa all diapered up. Reesa, however, wants to know how successful this is going to be so the shrink starts explaining her other patient. While explaining, Reesa ends up having an accident. Thankfully, they both agree, she was wearing her diaper.
Of course, the shrink can't just leave her there in a wet diaper, plus this is a good time to explain how to change one. So Reesa lays down while the shrink help cleans her up and instructs her how to diaper herself. Once finished, the shrink has to leave to meet another patient so Reesa decides to chill and strips down to just her bra and diaper before calling her mother.
